Worst customer service

Since Tuesday 03 February 2015 after submitting a change of banking details form for claims on funds due to me from my previous membership number. I have been calling since Wednesday to check if the form was correctly completed. On Thursday I was advised to call on Friday which I did and spoke to a call centre agent by the name of Unathi (PE) who advised me that the call has been closed by Zanele Xaba (JHB) who closed the call without checking why I've completed a change bank details form in 2015 and the system shows the last time details were updated in 2013, instead of her calling me to find out why I completed the request form she just decided to close the call without consulting with me regarding my inquiry. I thenspoke to a very helpful agent who later turned out dissapointing as she doesn't know what good customer service is. She promised to escalate my query to the creditors department for my query to be resolved or looked into and that she would call me on Monday which she never did. I am disgusted and dissapointed at the same time as to why must we clients be treated like we nothing ang don't have value? I regret why I waisted my time calling everyday just to be **** to.
